Wavefront Engineering Research Group

The Wavefront Engineering Research Group (WavEng) is a research unit within the Applied Physics and Optics Department at the Universitat de Barcelona . The team is composed by four permanent researchers, one post-doc fellow and several graduate and undergraduate students. The research of the group is focused on the following topics:
  • Vision systems based on wavefront coding.
  • Development of computational tools in optics, such as the determination of optical constants of thin film materials or the electromagnetic description of light beams.
  • Research on education in optics.

This false-color four-leaf clover-like image represents the x component of the TM term of the magnetic field of a highly focused gaussian beam (beam waist radius 0.4 lambda) at z=0. The inner structure (the tiny four red spots) clearly shows that the contribution of the evanescent term is not negligible.
